Suicide, taking your own life, is a tragic reaction to stressful life situations — and all the more tragic because suicide can be prevented. Whether you're considering suicide or know someone who feels suicidal, learn suicide warning signs and how to reach out for immediate help and professional treatment. You may save a life — your own or someone else's.

It may seem like there's no way to solve your problems and that suicide is the only way to end the pain. But you can take steps to stay safe — and start enjoying your life again.

Suicide warning signs or suicidal thoughts include:

Talking about suicide — for example, making statements such as "I'm going to kill myself," "I wish I were dead" or "I wish I hadn't been born"

Getting the means to take your own life, such as buying a gun or stockpiling pills

Withdrawing from social contact and wanting to be left alone

Having mood swings, such as being emotionally high one day and deeply discouraged the next

Being preoccupied with death, dying or violence

Feeling trapped or hopeless about a situation

Increasing use of alcohol or drugs

Changing normal routine, including eating or sleeping patterns

Doing risky or self-destructive things, such as using drugs or driving recklessly

Giving away belongings or getting affairs in order when there's no other logical explanation for doing this

Saying goodbye to people as if they won't be seen again

Developing personality changes or being severely anxious or agitated, particularly when experiencing some of the warning signs listed above

Warning signs aren't always obvious, and they may vary from person to person. Some people make their intentions clear, while others keep suicidal thoughts and feelings secret.

When to see a doctor

If you're feeling suicidal, but you aren't immediately thinking of hurting yourself:

Reach out to a close friend or loved one — even though it may be hard to talk about your feelings

Contact a minister, spiritual leader or someone in your faith community

Call a suicide hotline

Make an appointment with your doctor, other health care provider or mental health provider

Suicidal thinking doesn't get better on its own — so get help.

Suicidal thoughts have many causes. Most often, suicidal thoughts are the result of feeling like you can't cope when you're faced with what seems to be an overwhelming life situation. If you don't have hope for the future, you may mistakenly think suicide is a solution. You may experience a sort of tunnel vision, where in the middle of a crisis you believe suicide is the only way out.

There also may be a genetic link to suicide. People who complete suicide or who have suicidal thoughts or behavior are more likely to have a family history of suicide.

Although attempted suicide is more frequent for women, men are more likely than women to complete suicide because they typically use more-effective methods, such as a firearm.

You may be at risk of suicide if you:

Feel hopeless, worthless, agitated, socially isolated or lonely

Experience a stressful life event, such as the loss of a loved one, military service, a breakup, or financial or legal problems

Have a substance abuse problem — alcohol and drug abuse can worsen thoughts of suicide and make you feel reckless or impulsive enough to act on your thoughts

Have suicidal thoughts and have access to firearms in your home

Have an underlying psychiatric disorder, such as major depression, post-traumatic stress disorder or bipolar disorder

Have a family history of mental disorders, substance abuse, suicide, or violence, including physical or sexual abuse

Have a medical condition that can be linked to depression and suicidal thinking, such as chronic disease, chronic pain or terminal illness

Are lesbian, gay, bisexual or transgender with an unsupportive family or in a hostile environment

Attempted suicide before

Children and teenagers

Suicide in children and teenagers often follows stressful life events. What a young person sees as serious and insurmountable may seem minor to an adult — such as problems in school or the loss of a friendship. In some cases, a child or teen may feel suicidal due to certain life circumstances that he or she may not want to talk about, such as:

Having a psychiatric disorder, including depression

Loss or conflict with close friends or family members

History of physical or sexual abuse

Problems with alcohol or drugs

Physical or medical issues, for example, becoming pregnant or having a sexually transmitted infection

Being the victim of bullying

Being uncertain of sexual orientation

Reading or hearing an account of suicide or knowing a peer who died by suicide

Murder and suicide

In rare cases, people who are suicidal are at risk of killing others and then themselves. Known as a homicide-suicide or murder-suicide, some risk factors include:

History of conflict with a spouse or romantic partner

Current family legal or financial problems

History of mental health problems, particularly depression

Alcohol or drug abuse

Having access to a firearm — nearly all murder-suicides are committed using a gun

Starting antidepressants and increased suicide risk

Most antidepressants are generally safe, but the Food and Drug Administration requires that all antidepressants carry black box warnings, the strictest warnings for prescriptions. In some cases, children, teenagers and young adults under 25 may have an increase in suicidal thoughts or behavior when taking antidepressants, especially in the first few weeks after starting or when the dose is changed.

However, keep in mind that antidepressants are more likely to reduce suicide risk in the long run by improving mood.

Suicidal thoughts and attempted suicide take an emotional toll. For instance, you may be so consumed by suicidal thoughts that you can't function in your daily life. And while many attempted suicides are impulsive acts during a moment of crisis, they can leave you with permanent serious or severe injuries, such as organ failure or brain damage.

For those left behind after a suicide — people known as survivors of suicide — grief, anger, depression and guilt are common.

When you call your primary care doctor to set up an appointment, you may be referred immediately to a psychiatrist. If you're in danger of killing yourself, your doctor may have you get emergency help at the hospital.

What you can do

Take these steps before your appointment:

Make a list of key personal information, including any major stresses or recent life changes.

Make a list of all medications, vitamins and other supplements that you're taking, and the doses.

Ask a family member or friend to the appointment if possible — someone who accompanies you may remember something that you missed or forgot.

Make a list of questions to ask your doctor.

Some basic questions to ask your doctor include:

Could my suicidal thoughts be linked to an underlying mental or physical health problem?

Will I need any tests for possible underlying conditions?

Do I need immediate treatment of some kind? What will that involve?

What are the alternatives to the approach that you're suggesting?

I have these other mental or physical health problems. How can I best manage them together?

Is there anything I can do to stay safe and feel better?

Should I see a psychiatrist?

Is there a generic alternative to the medicine you're prescribing me?

Are there any brochures or other printed material that I can have? What websites do you recommend?

Don't hesitate to ask additional questions.

What to expect from your doctor

Your doctor is likely to ask you a number of questions. Be ready to answer them to save time to go over topics you want to focus on.

When did you first begin having suicidal thoughts?

Have your suicidal thoughts been continuous or occasional?

Have you ever tried to take your own life?

Do you have a plan to kill yourself?

If you have a plan, does it involve a specific method, place or time?

Have you made any preparations, such as gathering pills or writing suicide notes?

Do you feel like you can control your impulses when you feel like killing or hurting yourself?

Do you have friends or family members you can talk to or go to for help?

Do you drink alcohol, and if so, how much and how often?

What medications do you take?

Do you use recreational drugs?

What, if anything, helps you deal with your suicidal thoughts?

What, if anything, appears to worsen your suicidal thoughts?

What are your feelings about the future? Do you have any hope that things will improve?

What you can do in the meantime

If you've scheduled an appointment and can't see your doctor immediately, make sure you stay safe. Contact family members, friends or other people you trust to help you. If you feel you're in danger of hurting yourself or attempting suicide, call 911 or get emergency help immediately.

Your doctor may do a physical exam, tests and in-depth questioning about your mental and physical health to help determine what may be causing your suicidal thinking and to determine the best treatment.

Assessments may include:

Mental health conditions. In most cases, suicidal thoughts are linked to an underlying mental health issue that can be treated. If this is the case, you may need to see a doctor who specializes in diagnosing and treating mental illness (psychiatrist) or other mental health provider.

Physical health conditions. In some cases, suicidal thinking may be linked to an underlying physical health problem. You may need blood tests and other tests to determine whether this is the case.

Alcohol and drug misuse. For many people, alcohol or drugs play a role in suicidal thinking and completed suicide. Your doctor will want to know whether you have any problems with alcohol or drug use — such as bingeing or being unable to cut back or quit using alcohol or drugs on your own. Many people who feel suicidal need treatment to help them stop using alcohol or drugs to reduce their suicidal feelings.

Medications. In some people, certain prescription or over-the-counter drugs can cause suicidal feelings. Tell your doctor about any medications you take to see whether they could be linked to your suicidal thinking.

Children and teenagers

Children who are feeling suicidal usually need to see a psychiatrist or psychologist experienced in diagnosing and treating children with mental health problems. The doctor will want to get an accurate picture of what's going on from a variety of sources, such as the young person, parents or guardians, others close to the child, school reports, and previous medical or psychiatric evaluations.

Treatment of suicidal thoughts and behavior depends on your specific situation, including your level of suicide risk and what underlying problems may be causing your suicidal thoughts or behavior.

Emergencies

If you've attempted suicide and you're injured:

Call 911 or your local emergency number.

Have someone else call if you're not alone.

If you're not injured, but you're at immediate risk of harming yourself:

Call 911 or your local emergency number.

Call a suicide hotline number — in the U.S., call the National Suicide Prevention Lifeline at 800-273-TALK (800-273-8255) to reach a trained counselor. Use that same number and press "1" to reach the Veterans Crisis Line.

At the emergency room, you'll be treated for any injuries. The doctor will ask you questions and may examine you, looking for recent or past signs of attempted suicide. Depending on your state of mind, you may need medications to calm you or to ease symptoms of an underlying mental illness, such as depression.

Your doctor may want you to stay in the hospital long enough to make sure any treatments are working, that you'll be safe when you leave and that you'll get the follow-up treatment you need.

Nonemergency situations

If you have suicidal thoughts, but aren't in a crisis situation, you may need outpatient treatment. This treatment may include:

Psychotherapy. In psychotherapy, also called psychological counseling or talk therapy, you explore the issues that make you feel suicidal and learn skills to help manage emotions more effectively. You and your therapist can work together to develop a treatment plan and goals.

Medications. Antidepressants, antipsychotic medications, anti-anxiety medications and other medications for mental illness can help reduce symptoms, which can help you feel less suicidal.

Addiction treatment. Treatment for drug or alcohol addiction can include detoxification, addiction treatment programs and self-help group meetings.

Family support and education. Your loved ones can be both a source of support and conflict. Involving them in treatment can help them understand what you're going through, give them better coping skills, and improve family communication and relationships.

Helping a loved one

If you have a loved one who has attempted suicide, or if you think your loved one may be in danger of doing so, get emergency help.

If you have a loved one you think may be considering suicide, have an open and honest discussion about your concerns. You may not be able to force someone to seek professional care, but you can offer encouragement and support. You can also help your loved one find a qualified doctor or mental health provider and make an appointment. You can even offer to go along.

Supporting a loved one who is chronically suicidal can be stressful and exhausting. You may be afraid and feel guilty and helpless. Take advantage of resources about suicide and suicide prevention so that you have information and tools to take action when needed. Also, take care of yourself by getting support from family, friends, organizations and professionals.

There's no substitute for professional help when it comes to treating suicidal thinking and preventing suicide. However, there are a few things that may reduce suicide risk:

Avoid drugs and alcohol. Alcohol and street drugs can worsen suicidal thoughts. They can also make you feel less inhibited, which means you're more likely to act on your thoughts.

Form a strong support network. That may include family, friends or members of your church, synagogue or other place of worship. Religious practice has been shown to help reduce the risk of suicide.

Get active. Physical activity and exercise have been shown to reduce depression symptoms. Consider walking, jogging, swimming, gardening or taking up another form of physical activity that you enjoy.

Don't try to manage suicidal thoughts or behavior entirely on your own. You need professional help and support to overcome the problems linked to suicidal thinking. In addition:

Go to your appointments. Don't skip therapy sessions or doctor's appointments, even if you don't want to go or don't feel like you need to.

Take medications as directed. Even if you're feeling well, don't skip your medications. If you stop, your suicidal feelings may come back. You could also experience withdrawal-like symptoms from abruptly stopping an antidepressant or other medication.

Learn about your condition. Learning about your condition can empower and motivate you to stick to your treatment plan. If you have depression, for instance, learn about its causes and treatments.

Pay attention to warning signs. Work with your doctor or therapist to learn what might trigger your suicidal feelings. Learn to spot the danger signs early, and decide what steps to take ahead of time. Contact your doctor or therapist if you notice any changes in how you feel. Consider involving family members or friends in watching for warning signs.

Make a plan so you know what to do if suicidal thoughts return. You may want to make a written agreement with a mental health provider or a loved one to help you anticipate the right steps to take when you don't have the best judgment. Clearly stating your suicidal intention with your therapist makes it possible to anticipate it and address it.

Eliminate potential means of killing yourself. If you think you might act on suicidal thoughts, immediately get rid of any potential means of killing yourself, such as firearms, knives or dangerous medications. If you take medications that have a potential for overdose, have a family member or friend give you your medications as prescribed.

Seek help from a support group. A number of organizations are available to help you cope with suicidal thinking and recognize that there are many options in your life other than suicide.

To help keep yourself from feeling suicidal:

Get the treatment you need. If you don't treat the underlying cause, your suicidal thoughts are likely to return. You may feel embarrassed to seek treatment for mental health problems, but getting the right treatment for depression, substance misuse or another underlying problem will make you feel better about life — and help keep you safe.

Establish your support network. It may be hard to talk about suicidal feelings, and your friends and family may not fully understand why you feel the way you do. Reach out anyway, and make sure the people who care about you know what's going on and are there when you need them. You may also want to get help from your place of worship, support groups or other community resources. Feeling connected and supported can help reduce suicide risk.

Remember, suicidal feelings are temporary. If you feel hopeless or that life's not worth living anymore, remember that treatment can help you regain your perspective — and life will get better. Take one step at a time and don't act impulsively.
